A fluid specimen testing device having a removable lid which carries at least one testing strip behind a transparent top viewing window. The apparatus comprises a block of material with pre-determined dimensions related to the standard or custom dimensions of the frame and standard or custom dimensions of a subsequent stud and dry wall to be installed. The reduced-power beam is aligned in a test alignment such that it forms a beam spot on the coupling surface of the waveguide. These multipliers can be used in a risk analysis.
